Abstract

The invention concerns a chemical or biochemical analyser comprising a pair of automatic sampling units (66A, 66B) operating independently, each equipped with a retractable suction pipette (68A, 68B) for transferring predetermined amounts of samples and reagents from the tray (14) to a reaction vessel (22) of an analysing module. The reaction vessel (22) is heated by convection by means of a heating plate (54) arranged proximate to the lower portion of the wells (23), and controlled by a heat-sensing regulating circuit (58). A fast preheating device (72) is incorporated in the sampling unit (66A) for preheating the reactive liquid before it is introduced into the wells (23) of the reaction vessel (22). A mixing device (84) is controlled by a relay magnet (86) to provoke a reciprocating oscillating movement of the pipette (68A) when the latter is in lowered position in the well (23) of the reaction vessel (22) so as to stir the mixture of samples and reagents.
